IMPROVEMENT IN GEARINGS FOR WINDLASSES.

Specification forming part of Letters Patent No. LSEAQ, dated Mey 26, 1874; application filed Api-i118, 1874.

To all whom it may concern 'Be it known that I, Devin E. Mvnns, of Logansport, in the county'ot' Cass and State ot Indiana,.have invented a new and valuable Improvement in Mechanical Movements; and I do hereby declare that the following is a l'ull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings making a part of this specification, and to the letters and ligures otl reference marked thereon.

Figure l ofthe drawing is a representation of a cross-section of my device and Fig. 2 is a face view, part sectional, ot' the same.

This invention has relation to mechanical movements, and is designed for elevating heavy bodies, for drawing vehicles, and for other purposes where great power is required to perform the work.

It consists in combining, with a stationary inside spur-wheel, a revolving loaded spider, carrying large and small spur-wheels, which spider is applied on a revolving shaft, and actuated by a pinion spur-wheel and a belt-pnlley applied loosely on said shaft, as will be hereinatter explained.

In the annexed drawings, A designates a loundation, from which three standards, B B B', rise perpendieularly, constituting the supporting frame of the new mechanical movement. C designates ahorizontal shaft,whieh has its bearings in the standards B B', and is i'ree to turn therein. One end of the shaft C passes through the center ot' an internal spurwheel,D, which is rigidly secured to the standard B. E designates what I denominate a spider, which is rigidly secured upon the shaft C alongside of the spur-wheel D, and

' adapted to aii'ord a bearing fora short shaft,

a, carrying a pinion spur-wheel, b, and a large spur-wheel, c. That end of the spider E opposite to the end b c is loaded and provided with a curved guide, which covers part of the teeth of the wheel D, as shown in Fig. l. The pinion b engages with the teeth of a xed wheel, D, and the spur-wheel c engages with a pinion, g, which is keyed on one end of a short tubular shaft, h, turning loosely on the shaft C. 0n this tubular shaft h two grooved wheels, c and f, are keyed, around one ot' which a rope er cable, t', is applied, one end ot which is made fast to the Afoundation A, and the other end is made fast to the lever F, pivoted to saidfoundation. By depressing the lever F the ropet' will tightly embrace the wheel c, and operate as a friction-brake. rlhe wheel f is intended to receive upon it an endless belt, which communicates rotary motion to it from any convenient prime motor. On the shatt C a drum or reel, G, is keyed, around which is applied a rope for elevating or drawing objects. rIhe machine herein described may be applied to a carriage, and thus made portable; or it may7 be fixed to some established object.

The machine, as shown in the drawings, is arranged as an elevator, and when rotary motion is applied to the wheel f, as described, this motion will be transmitted to the shatt U through the medium of the wheels g, c, b, and D, andthe spider E, which latter, being loaded as described, will balance the movements and cause them to run regularly.

That I claim as new, and desire to secure by Letters Patent, is-

The revolving loaded spider E, carrying onv
